These corals come in often and claim to be aquacultured but they are absolutly maricultured corals. I think they ride a funky line by growing them out slightly in shallow raceways while having fresh ocean water ran into them constantly. That for me makes it a mariculture coral but some people will argue over this until the sun goes down. You will find mollusks and acropora crabs on the majority of these corals and you do not find those things in aquacultured grown corals. I had 5 colonies like these that came in via sea dwelling creatures in LA. Everything was doing great and the colors in the millepora were incredible. The older ones I've had for almost a year. I had a big alk swing to almost 11dkh last month and was able to get everything back to normal but starting last week all my millepora started to rtn quickly followed by my other colonies that were maricultured. Im down to one remaining colony and its not in the best shape. Still not sure if it was the alk swing or something else that caused all of it. My other colonies that I've gotten as frags rebounded pretty quickly and I haven't suffered any losses on those.
Its a gamble with these corals. I had good luck for a while and the only incident I can point to for stressing out the colonies and starting my RTN troubles was that alk swing. If you decide to go for it I would recommend cutting a couple chunks from each colony and getting them into different systems just to help safeguard your investment if something goes wrong in one tank.
here are some of my colonies before the RTN started. I haven't wanted to take any pictures this last week, its been a little heartbreaking for me.
